Hasn't Ollie Watkins extended his contract with Aston Villa after his outstanding performances this season? If Manchester United are interested in the Aston Villa striker then he is indeed a better striker than Hojlund but I don't think this will be an easy offer for him because of course Aston Villa will keep Ollie Watkins because he has been productive with many goals this season.
But still never look at the benefits alone because Ollie Watkins is a great player, he is still quite ideal age with 28 years now then his career is still long at Aston Villa as long as his performance is good enough, but so far only rumors not necessarily Aston Villa will release him especially for the preparation of the Champion League next season.
We should understand this simple facts about the system when it comes to making signings. There are players that are in their prime and it all ends when they finally exits this particular mediocre team and go for elite team, where most of them have failed woefully and couldn't deliver at top level.nManchester United shouldn't rush into preparing bids for Ollie Watkins because he's doing a nice job for Aston Villa. He deliver exceptional contributions but it doesn't mean there's no significant signings to make.
Manchester United is very unlucky when it comes to transfers. They cannot get any benefit from whichever player they put into the team. Jadon Sancho, Amrabat, Antony are some of these players. So even if Watkins comes, will they be able to get enough performance from him? That's why I think they should try their luck, but it's up to the technical team to make the players better.
